TECH NEWS - Dreams Come True As An Indian Invents A Machine That Converts AIR TO WATER

The answer to Bengaluru's water crisis, it seems, is blowing in the wind. Researchers at the city-based Scalene Energy Research Institute (SERI) have developed a Rain Tunnel - a technology that harnesses water vapour in the air and converts it into drinking water.

Available for domestic as well as commercial use once production begins next month, the former is capable of producing 30 litres of clean, filtered, drinking water within 24 hours. The commercial setup will produce a 1,000 litres in the same period of time. A plug-and-use model for domestic use will cost Rs 50-55,000.
Work on the Rain Tunnel began four years ago at SERI, a 24-year-old organisation that does research in healthcare; energy; water and food. The technology was also patented about one and a half years ago.

How It Works

A one cubic feet box draws in the air with an air circulator, which is then passed through a PM 2.5 microns filter "to remove the particulate matter and pollution," Kumar explains. Next step: UV, to kill all the airborne bacteria and viruses. Then, the temperature, pressure and flow rate is adjusted (depending on the atmospheric pressure of the location) to create an atmosphere suitable to agglomerate the water vapour to form clouds, "just like it takes place in nature," Kumar explains, asking us to think of a cloudy day. "Doesn't the humidity rise and air pressure fall before it rains?" This is where the Rain Tunnel is unique - it uses hypersonic sound waves to precipitate the concentrated water vapour. "We take a small quantity of seed water and subject it to a few million cycles of high frequency sound. This breaks them down and generates nano water particles, which we then freeze into ice crystals." Nano crystals don't require a very low temperature to freeze. The resultant nano ice crystals, as per the property of ice, begin to absorb more water vapour, and swell. "And the bigger they get, they lose that property, begin to melt into water, which falls as rain and is collected in a drip tray and into a tank. It then passes through four stages of filtration - sediment filtering, carbon filtering, ultra filtering at .04 microns and UV exposure - from which it is sent to the dispenser. As people draw water from the dispenser, more water is instantaneously filtered and sterlised and makes its way in."
Once the machine is plugged into an electrical socket and switched on, within 10-15 hours, it starts dispensing water. "And once the dry air - from which the water vapour has been removed - is let out, it will absorb more water and the cycle continues," Kumar adds, describing how one litre of water removed will produce another litre and so on.
I HOPE THIS GETS TO NIGERIA ,IT WOULD DO US A LOT OF GOOD. WINKS
